Optimized topology control in mobile IP networks using a new parametric routing algorithm

Abstract

When some intermediate nodes fail or are suddenly removed in a mobile IP network, a node failure can disconnect paths and decrease network efficiency due to loss of some packets. In this case, the movement of the remaining nodes must be controlled such that to prevent further network efficiency drop. In the present research, we will study the intermediate node failure and changing foreign networks in mobile IP networks when the Mobile Node (MN) moves. Then, a new optimal routing algorithm is proposed to make up the node failure and changing Foreign Agent (FA). For this purpose, an Optimal Parametric Topology Control Routing (OPTCR) algorithm is introduced based on parametric linear programming formulation (LPF). Since OPTCR can handle the handover latency, it is supposed that both destination and intermediate nodes can move but just intermediate nodes may fail. Simulation results show that OPTCR algorithm is superior to some algorithms appeared in the recent literature.

Optimizing Open‐Pit Truck Route Based on Minimization of Time‐Varying Transport Energy Consumption

“…Choi and Nieto [17] proposed a modified least cost path analysis algorithm that is applicable to areas with all types of roads and can compare the influence of terrain and curve variation on transportation efficiency. Furthermore, a series of models have been developed in logistics [18][19][20], transportation [21][22][23][24], and Internet routing [25,26], where each has particular focuses, advantages, and disadvantages. However, these methods are challenging to directly apply to the problem of route optimization for open-pit mine, because, in practical scenarios, transport conditions are constrained by a variety of comprehensive factors, and the transport cost model, which is stochastic and dynamic, is not equivalent to the shortest physical distance between nodes or the single static constants associated with transport cost.…”
